Ion specificity towards structure-property correlation of poly (ethylene oxide) [PEO]-NH4I and PEO-KBr composite solid polymer electrolyte

Influence of SiO2 Filler on the Property Enhancement and Endurance of Poly(ethylene oxide)–Salt Composite

“…The intercept on real axis gives the magnitude of bulk resistance ( R b ). The lower bulk resistance and high conductive nature of PN‐series using Nyquist plot is already established in our earlier communication . Consequently, the impedance of PN‐series with passive silica is found to lower as expected.…”

“…It can be mentioned that, irrespective of the salt content (from 5% to 20 wt%), PN‐series samples are found to be more conductive than PK‐series. This fact is already established in our earlier communication with proper justification and using Rice and Roth model . This section is intended to highlight the role of passive treated silica filler toward enhancement of ionic conductivity of the polymer salt composite.…”

“…The procedure stated here for polymer–salt composite was already established in the Patla et al. communication . Appropriate amount of pure PEO from B.D.H, England ( M w 10 5 ) was added to the previously prepared salt (Potassium Bromide (KBr) ( M w = 119) and/or ammonium iodide (NH 4 I) (5% and 20% of the polymer content)) solution.…”

“…The present context tends to report the influence of processed silica as a filler on the endurance of PEO based electrolyte films. Detailed study on ion specificity toward the functionalization of PEO–NH 4 I and PEO–KBr composite films has already been conducted by our group . In the present article, selected batches from PEO–NH 4 I and PEO–KBr series are used for self‐standing film preparation using processed silica as filler in variable contents.…”

Nanofiller-Induced Ionic Conductivity Enhancement and Relaxation Property Analysis of the Blend Polymer Electrolyte Using Non-Debye Electric Field Relaxation Function

“…The ε′ value identifies the amount of electric energy stored from the external field. The maximum value of dielectric constant at lower frequencies and a decrease in its value at higher frequency suggest that the system behaves like a polar dielectric. − The increase in dielectric constant and the decrease in the magnitude of the corresponding tangent loss of the composite in the presence of filler is due to the formation of the interphase region as described in Figure . Such an interphase region enhances the probability of the localized hopping instead of long range ion transportation .…”
